Abstract: PURPOSE: To generate a microwave signal whose undesired wave component is reduced. CONSTITUTION: A reference signal from a reference signal oscillator 1 and a microwave signal outputted from a microwave band voltage controlled oscillator 3 via a microwave band pass filter 6 are given to a sampling phase comparator 2. Then a phase of a reference signal outputted from the reference signal oscillator 1 and a phase of the micro wave outputted via the microw ave band pass filter 6 from the voltage controlled oscillator 3 are compared by the sampling phase comparator 2, its phase difference signal is fed back to the voltage controlled oscillator 3 via a loop filter 4 to form a phase locked loop.  The sampling phase comparator 2 multiplies the reference signal to generate the sampling clock and an undesired wave component is generated, since the undesired wave is arisen in a block band of the microwave band pass filter 6, the undesired wave component attenuated by a block attenuation is outputted from an output terminal 5 of the voltage controlled oscillator 3.
